Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue of MDPI Plants journal on "Exploring Plant Responses to Stress and Disease." This issue aims to shed light on the intricate mechanisms by which plants respond to various stressors and combat diseases, offering insights into the adaptation and resilience of plant species.

Plants are continuously exposed to a multitude of stress factors, including abiotic stresses such as drought, heat, salinity, and pollution, as well as biotic stresses like pathogens and pests. Understanding how plants perceive and respond to these stressors is of the utmost importance to ensuring sustainable agricultural practices and mitigating crop losses. Additionally, uncovering the molecular, physiological, and genetic mechanisms underlying plant defenses against diseases holds great potential for developing novel strategies for disease management.

This Special Issue invites contributions that delve into different aspects of plant responses to stress and disease. We welcome original research articles, reviews, and perspectives that explore a wide range of topics, including but not limited to:

  1. Phenotypic responses to stress and diseases.
  2. Molecular and genetic basis of stress tolerance in plants.
  3. Signaling pathways involved in stress perception and response.
  4. Physiological and biochemical adaptations to abiotic and biotic stresses.
  5. Defense mechanisms against pathogens and pests.
  6. Interactions between plants and beneficial microbes for stress alleviation.
  7. Novel technologies and approaches for studying plant stress responses.
  8. Strategies for enhancing stress tolerance and disease resistance in crops.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Plant non-specific lipid transfer proteins (nsLTPs) are small proteins capable of transferring phospholipids between membranes and binding non-specifically fatty acids in vitro.

Plant non-specific lipid transfer proteins (nsLTPs) are small proteins capable of transferring phospholipids between membranes and binding non-specifically fatty acids in vitro. They constitute large gene families in plants, e.g., 83 in potato (Solanum tuberosum). Despite their recognition decades ago, very few have been functionally characterized. Here, we set out to better understand the function of one of the potato members, StnsLTPI.33. Using quantitative polymerase chain reaction, we show that StnsLTPI.33 is expressed throughout the potato plant, but at relatively higher levels in roots and leaves compared to petals, anthers, and the ovary. We also show that ectopically-expressed StnsLTPI.33 fused to green fluorescent protein colocalized with an apoplastic marker in Nicotiana benthamiana leaves, indicating that StnsLTPI.33 is targeted to the apoplast. Constitutive overexpression of the StnsLTPI.33 gene in potato led to increased levels of superoxide anions and reduced plant growth, particularly under salt stress conditions, and enhanced susceptibility to Alternaria solani. In addition, StnsLTPI.33-overexpressing plants had a depleted leaf pool of pipecolic acid, threonic acid, and glycine, while they accumulated putrescine. To our knowledge, this is the first report of an nsLTP that is associated with enhanced susceptibility to a pathogen in potato. Full article
